Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

Caerphilly Mountain is located in the Vale of Glamorgan in Caerphilly and stands at 271 m above sea level. There are some magnificent panoramic views on offer here across Cardiff and Caerphilly, Feet, and on a sunny day, even over to Flat Home and Steep Home Islands, a pair of welsh islands lying in the Bristol Channel.

The earliest evidence of settlement at Ruperra is from between around 700 BC and 100 AD, when an Iron Age Hill Fort was constructed along the ridge of Coed Craig Ruperra. The splendid panoramic views from the top of the ridge would have given the site a strategically strong position. Defensive banks and ditches are still visible around the area of the mound, and continuing work on the site will reveal these more clearly. This hill fort lies within what would have been the tribal territory of a people the Romans called the Silures, who were a fiercely independent nation inhabiting the vale of Glamorgan, Gwent and the valleys

Lovely place to visit you can walk up to the top where there’s a grassy platform. Great views across the forest and out to the sea. Definitely worth a visit
